Subject: virtio-net: new section mismatch warning. revert patch?
Date: Wed, 4 Nov 2009 16:17:30 +0200	[thread overview]
Message-ID: <20091104141729.GA27288@redhat.com> (raw)

With v2.6.32-rcX I started getting section mismatch warnings for
virtio_net.
make with CONFIG_DEBUG_SECTION_MISMATCH=y shows:

WARNING: drivers/net/virtio_net.o(.data+0x90): Section mismatch in
reference from the variable virtio_net to the function
.devexit.text:virtnet_remove()                                                                    
The variable virtio_net references                                                                            
the function __devexit virtnet_remove()                                                                       
If the reference is valid then annotate the                                                                   
variable with __exit* (see linux/init.h) or name the variable:                                                
*driver, *_template, *_timer, *_sht, *_ops, *_probe, *_probe_one, *_console,                                  

virtnet_remove was converted to devexit by this commit:

	commit 3d1285beff2e8467b8c3884d83b7a91a99aa9fcd
	Author: Uwe Kleine-König <u.kleine-koenig@pengutronix.de>
	Date:   Wed Sep 30 22:28:34 2009 +0000

	    move virtnet_remove to .devexit.text

We didn't have these warnings in v2.6.31, so this is a regression.
revert?
